For the majority of the time it is almost impossible to make any sense out of bipolar mood swings. More often than not it has next to nothing to do with circumstances, other than the sadness and ‘depression’ that ‘normal’ people experience when things go wrong. If this cycle was all to do with circumstances then I would have the power to turn it around, but I have no clue what happened to my mind last week when- at the start- I had to be wrestled of the top of a bridge by my confused and desperate boyfriend.
